Is this a Swedish coin? [επιλυμένο]

Good day! Can you guys help me identify this coin? It might be 1 Öre Kopparmynt - Fredrik I (1720-1750) or ½ Öre Silvermynt - Fredrik I (1720-1721). But "F.R.S." is really close to the edge. Maybe it's a completely different coin. It's around 24 mm wide. Thanks!

Hello! I try to put this coin on powerpoint and put two lines.
The coin diameter is exactly 24 mm. I am not sure but may be this is 1/2 Ore (24 mm ) not 1 Ore (23.1 mm) but I don't know on 100%.

​Thank you very much! I really appreciate it. Let's see what other users will say.

Both side show that the coin is struck on another coin.
Very nice overstrike

​Thank you for pointing it out! I'd have never figured it out. Do you think it was done by the bank? Wikipedia says overstriking was a common practice in the past.

Yes the 'National Mint' did used old coins for restriking.

​OK, thank you very much! If the bank did it, then I guess my coin has some value. ))) I can't seem to determine whether it's ½ Öre Silvermynt - Fredrik I or 1 Öre Silvermynt - Fredrik I. I think it's the former, because 1) my coin is 24 mm and 2) the crowns on obverse look similar to the ones on the 1/2 coin. I might be wrong, though
